ath9k: Remove a few unused functions

Browse Source 
ATH9K_ANT_VARIABLE is the default diversity control used.
Consequently ath9k_hw_decrease_chain_power() does nothing.
ath9k_hw_setantennaswitch() is unused too.

Also, gbeacon_rate is unused.

* ath9k_hw_decrease_chain_power()
*
* @ah: atheros hardware structure
* @chan:
*
* Only used on the AR5416 and AR5418 with the external AR2133/AR5133 radios.
*
* Sets a chain internal RF path to the lowest output power. Any
* further writes to bank6 after this setting will override these
* changes. Thus this function must be the last function in the
* sequence to modify bank 6.
*
* This function must be called after ar5416SetRfRegs() which is
* called from ath9k_hw_process_ini() due to swizzling of bank 6.
* Depends on ah->analogBank6Data being initialized by
* ath9k_hw_set_rf_regs()
*
* Additional additive reduction in power -
* change chain's switch table so chain's tx state is actually the rx
* state value. May produce different results in 2GHz/5GHz as well as
* board to board but in general should be a reduction.
*
* Activated by #ifdef ALTER_SWITCH. Not tried yet. If so, must be
* called after ah->eep_ops->set_board_values() due to RMW of
* PHY_SWITCH_CHAIN_0.
